Abstract

A solar battery which has thin film type of single crystal silicon, and a method for manufacturing such a solar battery is disclosed. A transparent glass plate is adhered to an upper surface of a silicon substrate, having active regions to transform solar energy into electric energy. The bottom surface of the substrate is ground from hundreds of micrometers to several tens of micrometers, or even to several micrometers in thickness such that the substrate is semi-transparent or transparent. An anti-reflective layer is coated over the bottom surface of the substrate so as to increase the possibility for the incident light onto the solar battery to convert into electric energy and further improve the efficiency of energy transformation.
